When going over rough or uneven roads, the car produces a strong low-frequency resonance, like a bass-heavy "boom". This causes a very uncomfortable feeling of pressure changing in my ears, gives me a headache and ear pain whenever I drive in local roads, which is the majority of driving in my area. This causes me to need to pull over and stop the car frequently to readjust my hearing. I've found many reports from others of the same issue but Toyota have not acknowledged it or found a solution.
